Influence of the synergistic effect between Co–N–C and ceria on the catalytic performance for selective oxidation of ethylbenzene

A series of catalysts, i.e. metal oxides (MO) such as CeO₂, Fe₂O₃ and Al₂O₃ supported Co–N–C (Co–N–C/MO) were prepared by heating supported cobalt porphyrin in a N₂ atmosphere.
